Application January 5, 1948, Serial No. 586

1 Claim. 1

This invention relates to a fruit juice extractor which is especiallyadapted for extracting the juice from citrous fruit, employing means forsevering the fruit prior to the extraction of the juicetherefrom,`employing pressure plates for engaging the fruit at the topand bottom thereof for extracting the juice and employing one of thepressure plates as a strainer to strain the pulp and seeds from thejuice extracted.

The extractor as constructed, in accordance With the invention, will,therefore, simultaneously sever the fruit and extract and strain thejuice from the fruit with one manual operation.

With the above details, and advantages arising from the assembly ofthese details, in mind, the invention consists of the novel details ofconstruction, arrangement and combination of parts more fullyhereinafter described, claimed and illustrated in the accompanyingdrawings in which:

Figure 1 is an' elevational side view of an embodiment of the invention;

Figure 2 is a top plan view of Figure 1;

Figure 3 is an elevational view partly in section to show the variouselements of the device;

Figure 4 is a sectional View on the line 4-4 of Figure 3 and Figure 5 isan elevational view partly in section of the removable cup of thedevice.

Referring more in detail to the drawings, the reference numeral Idesignates the fruit juice extractor embodying the invention.

The extractor I Il embodies a cup-shaped housing or hopper II, which issupported in elevated position above a suitable plane surface by meansof relatively spaced vertically inclined legs I2.

The legs I2 are each provided with a foot or base I3, which retains theextractor in upright position. The legs I2 are spaced sufliciently apartto permit a glass or similar container I4 to be placed therebetween.

Removably positioned within the housing II, is a removable cup I5,which, on its exterior surface, conforms to the contour of the interiorsurface of the housing I I.

The housing II is provided with a dispensing spout I6, at the bottomthereof, and the cup I has an outlet opening I'I in its bottom inalinement with the spout I6.

Formed integrally with the cup I5, and extending from the front wallthereof to the rear wall thereof is the substantially triangular shapedfruit severing member I8. The apex of the mem-A ber I8 is serrated as atI9 to engage the fruit placed thereon for the severing thereof.

(Cl. 10D-41) Relatively spaced slots 20 are formed in the member I8,transversely thereof, and these slots extend upwardly from the bottom ofthe member to a point below the serrated apex I9. The bottom of themember I8 has a semi-circular shaped channel 2I forming communicationbetween the slots 20 and the opening Il in the cup,- shaped member I5.

A pressure plate and strainer 22 is mounted for movement within thecup-shaped member I5, and the contour of the peripheral edge of theplate 22 permits swinging movement of the plate 22. At the rear of theplate 22, there is formed a projection 23, which extends outwardly ofthe member I5 through the elongated opening 24 in the rear wall thereof,and the housing I I through the elongated opening 25 in the rear wallthereof. The openings 24 and 25 enable th-e strainer to slidably extendthrough such openings into the cup-shaped member. The projection 23engaging the lower edge 25 of the opening 25 forms the fulcrum for theplate 22 during the pivoted movement of the plate about the edge 25 ofthe opening 25.

Positioned centrally of the plate 22, is the V- shaped cutout or slot 26which, during the movement of the plate 22, will straddle the member I8.The plate performs its juice extracting operation by means of thestaggered relatively spaced rows of perforations 21.

Extending upwardly from the upper edge of the rear wall of the housing II, is the projection 28 which, at its upper end, forms the hinge means29 for the pressure plate 30.

On its upper surface, the plate carries the lever handle 3l for theoperation of the plate and rearwardly of the point of connection of thehandle with the plate 30, there is formed the upstanding projection 32.The plate 3U, cen- `trally thereof, is provided with the V-shaped cutoutor slot 33 which, in the operation of the plate 30, will straddle themember I8 in like manner as does the plate 22. l

In operation. the plate 30 is moved into the position shown in Figure 1.In this position, the projection 32, on the pressure plate 30, engagesthe projection 23 on the p late 22 to elevate the plate to a horizontalposition, as shown in Figure 1 in dotted lines.

The fruit 34 is then placed on the plate 22, and the plate 3D raised bymeans of the handle 3|. As the plate 30 is moved upwardly and downwardlyto engage the fruit, the projection 32 disengages from the projection23, and the plate 22 assumes the position shown in Figure 3.

Downward pressure on the handle 3| causes the plate 30 to force thefruit 34 against the serrated teeth of the member IB thereby severingthe fruit in half. Further pressure of the handle 3| causes the plate 3Uto compress the fruit 34 and extract the juice therefrom. The juicepasses through the slots 20 in the member I8, and out the spout I6 intothe container I4. The size of the slots 20 prevents seeds or pulp frombeing passed outwardly in thejuice. When the juice has been viinallyextracted from thefruit. the handle 3| is moved backwardly to theposition shown in Figure 1. As the plate 22 again moves into itshorizontal position, it will lraise A.the remains of the fruit outwardlyof the member I5. so that when the remains are disposed of, anotherpiece of fruit can be placed thereon and the previously describedoperation completed.

The extractor being made of a few parts, is easily cleaned andmaintained in a sanitary condition. It is inexpensive to manufacture anddurable and eiective in operation.

yFrom the foregoing description, it is believed that the constructionand operation of the extractor will be. apparent to those skilled in theart, and it is to be understood that changes in they minor detailsv ofAconstruction, arrangement and combination of parts may be resorted to,provided they fall Within the spirit of the invention and the scope ofthe appended claim.

lHavingl thus described the invention, what is claimedl as new anddesired to be secured by Letters :Patent is slidably extend through theopenings in the rear wall of the housing and member into said member, apressure plate pivoted to the upper rear edge of said housing. a handleon said pressure plate, said strainer having a projecting portionadapted to extend outwardly of the opening in the rear wall of thehousing, and a projection on said pressure plate adapted to engage theprojecton on said strainer so that the projecting portion of thestrainer vWillhave pivotal movement about the lower edge of theopeningin the rear wall of the housing to pivot said strainer to aV4 horizontalplane within said member when said pressure plate is extended to fullinactive position, said strainer and said pressure plate being .providedwith a cut-out adapted to straddle said cutter .during movement of saidstrainer and said plate, and said housing being provided with adischarge spout, said cup-shaped member having an opening in alignmentwith said spout. and said cutter being provided with achannelcommunicating with said opening` and vertically inclinedslotscommunicating with said channel. whereby juiceextracted from fruit.placed in said housing. is discharged outwardly thereof.
